Create two walk Animation

Hey Everyone, I have two simple 2d characters a boy and a girl, I want a simple 2d sprite walking animations for them. I have attached some photos here, i want you to crop the images and then make the walking animations, Or you can make the characters yourself which looks similar and then animate them. I just need the animation anyways. I have attached so many files, But don't panic, chose whichever you think is good for your work. I don't need them to be very detailed, they just need to be fluid. I will later use unity to convert the sprite sheet into animation. I need them urgent, And price matters.
